6 Claims. (Cl. 206-58) This invention relates to dispensing cartonsprovided with cutters.

The main objects of this invention are:

First, to provide in a dispensing carton a cutter structure whichconstitutes an effective reinforcement and binding for the wall to whichit is applied and acts to counteract the tendency of the wall to whichit is applied to bow outwardly.

Second, to provide in a dispensing carton a cutter of downwardly facingsection which embraces the edge of a wall of the carton and iseffectively secured thereto to constitute a reinforcement and bindingfor the wall to which it is applied.

Objects relating to details and economies of the invention will appearfrom the description to follow. The invention is defined in the claims.

A preferred embodiment of the invention is illustrated in theaccompanying drawing, in which:

Fig. l is a front perspective view of a dispensing carton embodying myinvention with a portion of the web of paper withdrawn from the carton.

Fig. 2 is an enlarged fragmentary section on a line corresponding toline 2-2 of Fig. 1.

Fig. 3 is an enlarged front elevational view.

Fig. 4 is an enlarged inside elevational view of the front wall andcutter thereof.

Fig. 5 is a plan view of the carton.

It will be understood that no attempt has been made to show the parts intheir relative proportions and in Fig. 2 the material of the carton, thematerial dispensed and the cutter are illustrated much thicker than theactual material used in the commercial structure.

Referring to the accompanying drawing, the carton designated generallyby the numeral 1 is of the collapsible type but as the details of thecollapsible features form no part of this invention they are not hereillustrated or described.

The carton illustrated comprises a front wall 2 and cover 3 having atucking flap adapted to be disposed at the inner side of the front wall.The paper 5, conventionally illustrated as being a transparent film orweb, is commonly in a roll loosely positioned in the carton. The web ofpaper is passed under the flap 4 and upwardly between the flap and thefront wall 2 as illustrated in Fig. 2.

The cutter designated by the numeral 6 is of downwardly facing channelor U-section, the bight portion 7 being upwardly curved. The lower edgesof the arms 9 and terminate in inturned flange-like portions 8 and 11.The arm 9 is substantially wider than the arm 10 so that both edges maybe substantially embedded in the wall, even when it is of thin stock, toprovide an effective grip thereon without materially severing orweakening the wall. The wall is clamped between the arms. The edge 111of the arm 10 is desirably positioned opposite the angle or bend in thearm 9. The cutter is provided with teeth 12, desirably A-shaped, whichare struck out from the bight portion of the cutter. The teeth arespaced at their bases and merge into the arm 9 of the cutter. Thisprovides bridge-like portions 13 between each adjacent pair of teethconnecting the arms 9 and 10 so that the cutter effectively resistsstresses in all directions. The tips of the teeth project above thebight of the cutter.

The cutter is substantially the length of the wall to which it isapplied and is disposed over the edge thereof and clamped thereon, andconstitutes an effective binding and reinforcing member therefor. Asshown in Fig. 4, the cutter is longitudinally curved inwardly and thecentral portion thereof is desirably in springable thrust engagementwith the material disposed between the cutter and the closure flapasshown in Fig. 2. This acts to retain the end of the dispensiblematerial in position for grasping and also the inward bowing of thecutter counteracts the outward pull on the material as the material isdrawn over the cutter preparatory to severing and while being severed.

Thus formed and arranged the cutter, even when formed of quite lightsheet metal stock as is the commercial practice, serves as an effectivebinding and reinforcement for the wall of the carton to which the cutteris applied and which is subjected to stress in dispensing the material.

I have illustrated the invention in an embodiment which has been foundvery practical. I have not attempted to illustrate or describe otheradaptations which I contemplate as it is believed this disclosure willenable the practice of the invention as may be desired.

Having thus described the invention what is claimed as new and desiredto secure by Letters Patent is:

l. A dispensing carton including a front wall and cover therefor havinga closure flap adapted to be positioned on the inner side of the frontwall, a cutter of downwardly facing U-shape having a bight portion andsubstantially parallel arms terminating in inwardly convergingflange-like edge portions, a series of teeth struck out from the bightportion with their bases spaced and merging into one arm of the cutterwith their tips projecting above the bight thereof, the portions of saidbight portion intermediate the spaced bases of the teeth integrallyconnecting the parallel arms of the cutter to each other, said cutterbeing of a length substantially that of the front wall and beingembracingly disposed over the edge of the front wall with the armsthereof in fixedly clamped engagement therewith, and with theflange-like edge portions of the arms in embedded engagement with thefront wall, said cutter constituting a reinforcing and binding elementfor the edge of the front wall and having the portion thereofintermediate the ends of the cutter bowed longitudinally of the cutterand inwardly relative to the carton and towards the closure flapdisposed on the inner side of the front wall whereby the central portionof the cutter is normally in springable thrust engagement with thedispensed material between it and the closure flap and whereby thecutter counteracts outward bending of the central portions of the cutterand front wall when the dispensed material is pulled out of the cartonand over the cutter preparatory to and while severing the material.

2. A dispensing carton including a front wall, a cutter of downwardlyfacing U-shape having a bight portion and substantially parallel armsterminating in inwardly converging flange-like portions, and a series ofteeth struck out from the bight portion with their bases spaced andmerging into one arm of the cutter with their tips projecting above thebight thereof, the portions of said bight portion intermediate thespaced bases of the teeth integrally connecting the parallel arms of thecutter to each other, said cutter being of a length substantially thatof the front wall and being embracingly disposed over the edge of thefront wall with the arms thereof in fixedly clamped engagement therewithand said cutter constituting a reinforcing and binding element for theedge of the front wall and having the central portion thereof bowedlongitudinally of the cutter and inwardly relative to the carton wh rebythe cutter counteracts outward bending of the central portions of thecutter and front wall when the dispensed material is pulled outwardly ofthe carton and over the cutter preparatory to and While severing thematerial.

3. A dispensing carton including a wall, and a cutter of downwardlyfacing channel section embracingly disposed over the edge of the walland having a series of integral teeth struck out from and projectingabove the bight portion thereof, the bases of the teeth being spaced,the arms of the cutter being integrally connected by bight portionsbetween each adjacent pair of teeth, said cutter being of a lengthcorresponding to the length of the wall and being normally curvedlongitudinally of the cutter and inwardly relative to the carton andbeing disa posed over the edge thereof with its arms retainingly clampedthereon whereby the cutter is secured to the wall and constitutes areinforcement binding for the edge thereof and supporting the edgenormally in an inwardly curved position.
